Outline of Annual Research Achievements

Using the unique equipment for annealing under controlled atmospheres, constructed in the first year of the project, the effect of both water vapour and carbon dioxide on oxygen exchange in lanthanum strontium cobalt ferrite (LSCF) and barium lanthanum cobaltite (BLC) have been measured as a function of temperature. Both of these components accelerate oxygen exchange compared to pure, dry oxygen on its own by around an order of magnitude. However, the activation energies for oxygen exchange in the different atmospheres do not seem to vary significantly.

Measurements of the surface composition of the samples exposed to different atmospheres suggest that both humidity and carbon dioxide exacerbate the segregation of alkaline earth cations (strontium and barium in LSCF and BLC, respectively).
